A TASER.RTM. and a vertical grip are combined to be attached to the stud post under the forend or the barrel of a conventional long arm. A TASER.RTM. may also be combined with the forend or barrel of a conventional long arm itself. Stud posts come standard on certain long arms like the M-16 rifle. Stud posts can be installed on single shot and pump action shotgun forends as well. The TASER.RTM. power supply can serve as a power source for a strobe lamp, which may be sighted by rescuers either visually or with infrared night viewing or other special viewing equipment for miles. The optical signal could be produced in the infrared, visible light and ultraviolet light regions of the electromagnetic spectrum. The signal lamp is inserted into a TASER.RTM.'s firing chamber in lieu of an ammunition cartridge.
